Update the MATE DE to 1.12.
* Still build MATE against gtk+ 2 due to gtk+ 3 support not ready
for prime time.
* Fix loading of a number of applets. We rename a number of applets
but didn't change the "config" files the "add applet to panel" dialog
uses. [1]
* Unbreak the creation of new notes with the stickynotes applet [2]

Say hello to Mate 1.6.
Mate is a lite desktop forked from gnome2.
Most of the work is done by Jeremy Messenger (mezz@). The only thing I did
was update a few ports to later 1.6 release and attempting to keep up with
ports infra changes. Resulting bugs are all mine.
Mate is a sort of replacement for Gnome 2. So people wanting to keep a
Gnome 2 like desktop should switch. Gnome 2 will be replaced by Gnome 3
in the near future. This switch will be announce with a transition time
so people have more time to switch if they haven't already.
This release was made possible by everyone that send friendly pokes to
keep mate on my mind.
